Speed of Light to Knots Converter
CommonMeters per second, km/h, mph and more.
How to convert Speed of Light to Knots
Multiply the speed of light value by 5.8275e+8: 1 c = 5.8275e+8 kn. Going the other way, 1 kn = 1.716e-9 c, so divide by 5.8275e+8 or use the Knots to Speed of Light converter.
About these units
Speed of Light (c)
The speed of light in a vacuum is exactly 299,792,458 meters per second. Nothing carrying information can travel faster, and it is used to define the meter.
Knots (kn)
A knot is one nautical mile per hour, exactly 1.852 km/h or about 1.151 mph. Ship and aircraft speeds and wind speeds at sea are given in knots.
